Carefully check the sack yield. Normal weight concrete is roughly 145 lbs/cu ft. Use greater than 3000 psi strength concrete. Do not add excess water. Rod the stiff mix into place. Note the 2 x 2 x 2 should be measured at least 6 inches below grade and so all surfaces are against firm to stiff soil. That means you will need extra concrete to finish above grade.
